e olaims, (cram-9s) This invention relates to an automatic dispensingdevice for containers, and the primary object of the same is to providean attachment in the nature of a stopper or cap for bottles and the likewhich will measure a predetermined quantity of liquid when the containeris inverted to pour and .which is reliable in operation, relativelysmall and neat in appearance and so simple in design and construction asto be capable of manufacture at a relatively low cost.

The foregoing and other objects and advantages will become apparent inview of the following description taken in conjunction with the drawing,

wherein: Figure 1 is a central sectional view of the improved dispensingdevice shown adapted for'use witha bottle, the latter being illustratedin dotted outline in upright position;

Fig. 2 is a view similar to Fig. 1, showing the position of certainparts when the bottle is in pouring position;

Fig. 3 is a view in elevation of thedevice;

Fig. 4 is an enlarged'view in central transverse section of theair-controlling cylinder and housing therefor; and,

Fig. 5 is an enlarged section taken on the line 5-5, Fig. 1. r

In its preferred form, the device comprises a delivery or pouring nozzleor spout 5 which, when adapted for a bottle stopper, is formed with anannular. shoulder or boss 6 and sleeve portion '7 over which is inserteda bottle stopper 8,.the latter being formed of cork, rubber compositionor like material. A hinged lid 50. is provided at the end of the nozzle5. I

Adjacent the delivery nozzle 5 is acylindrical housing 9. The pouringnozzle and housing are so designed that they may be die-cast in onepiece, and accordingly the parts 5, 6, '7 and 9 are'shown as oneintegral casting. The portion 7 hasfor'med therein a passageway 10 whichcommunicates with the interior of thebottle or like container through arestricted air-inlet opening 10a. Atits upper end, the passageway 10opens into 'a cham-- her or trap 11, adapted to receive any liquid thatmay pass through the opening 10a during the pouring operation. Tofacilitate the casting operation, the one side of the chamber 11 isinitially cast open and subsequently closed by a plate 11a, note Fig. 5,having inwardly projecting flanges which fit into the walls of the saidchamber.

The housing 9 is preferably cast at an incline with "respect to thenozzle or spout 5, and in the open end of this housing is inserted, anair-con trolling valve cylinder 12 having an open end portion formedwith an annular recessed shoulder 12a Q I adapted to engage the adjacentwall of the housing. In the open end of the cylinder 12 is inserted anadjustable air-inlet or vent plug'13 having a longitudinal port 13a inthe side wall 5 thereof, as shown in dotted outline in Fig. 4, the oneend of this port communicating with a hole or port 13b formed in theside wall of the housing and open to the atmosphere. A taperingadjusting groove 130 is formed in the side wall of the plug 13 and isarranged to override the port I 131). Thus by turning the plug 13anti-clockwise, the port 131) may be gradually closed, and by turning itclockwise, gradually opened, the adjustment being capable of accuratecontrol. g 1

.The cylinder 12 is provided with a relatively sensitive escapementvalve assembly in the form' of a leaf spring 14 and ball valve 14aadapted to close an exhaust port or vent 14b. The housing 9 defines achamber 15 around the cylinder 12.20 Air inlet ports 16,- 17, 18 and 19are formed in the one end and side wall of the housing 9, and in the endand sidewall of the cylinder 12. A longitudinal accelerating by-passvent 20 is formed.

in the side wall of the cylinder 12. 5 i

A floatingvalve piston'22 ismounted in the cylinder "12 and acts-toclose the ports 16 and 17 when the bottle is held in a pouring positionfor a predetermined length of time. I l

The device operates as follows: When the bottle is inverted ortilted'ito pouring position, air will pass from the atmosphere into thebottle through ports 16, 17, 18,19 and 10a, permittingliquid -to flowfrom thespoutor nozzle '5 until the piston 22 reaches the .end ofcylinder12 and closesthe portslfi and 17 (the position shown in Fig.2),whereupon air will be shut off from the bottle and the liquid will ceaseto flow; The rate'of travel of the piston 22 is governed by the volumebf-ai'r, admitted'through the ports 13b and- 13a'in'the housing 9 andplug 13. a

When the piston 22 passesthe longitudinal 'ven't 20, its speedis-accelerated, dueto the fact that the vacuum is abruptly broken, sothat the pistonin effect drops into the end of the cylinders Thisresults in an abrupt closing ofthe air-inlet ports 17 and 18 and aback-action on the fluid in the bottle which reduces/dripping to aminimum. 1 l

When the bottle is turned to its normal upright position, the piston 22slides by gravityback to the position shown in Fig.1, the weight of thepiston 22 being sufficient to .cause the air entrapped within thecylinder to lift the valve 14a and permit escapement thereof through theport 14b. By adjusting the size of the opening 13a,

the quantity of liquid dispensed at one pouring from the nozzle 5 may bevaried as desired. While some of the liquid in the container or bottlemay pass into the chamber or trap 11 when the bottle is tilted topouring position, yet the amount is negligible and does not interferewith the operation of the dispensing device, the liquid returning to thebattle when the latter is set :inupright position. i

The parts of the assembly are, in general, die

castings'which may be manufactured at rela- 'quantity of liquid. F#ItWill be understood that certain modifications andwar'iations instructurermay be adopted with- .:;in the-scope of the invention asdefined by the fappendedclaims. p
